More info on Penske shocks

@fooddude, I think you're beating a dead horse here.

I'd rather go for some JRZ RS's.

Hahaha..ya. I'll stop fussing over them.

..it's not like I'll ever be able to afford them anyways.. even if they were half price at $4k.

Nothing but a pipe dream by now, lol.

I'd still tak the Penske over JRZ. If I'm gonna spend that much it better have the rebuild ability and tunability of a Penske. How many different types of damper pistons does JRZ offer? Regressive valve? What about Penske? Exactly.

I wouldn't. The RS is not really in the same league.

I think it's cool Penske even decided to design and build a setup specific to the car. I talked to Anze originally about building a set and the cost was relatively similar but that was using external cans and a the 8300 series shock. It looks like Penske is including lower perches to fit the stock springs, like MCS did for people looking to use them in "Street" autocross classes.

Yeah.. I wouldn't want to daily drive on +10k coilovers.. If I was going to use these on a double duty car i'd probably learn how to swap out dampers on this car very quickly. Pit crew status before every track day...

You'd want to have your own alignment rack too then, or get VERY good at front end alignments without one.

You mean you can't just eyeball it? There was a whole thread about properly torquing something with an impact wrench, so this should be about the same, right?

Yeah that too. Mark my settings clearly and go from there. If I had 10k for dampers I'd think I would invest another thousand on some decent alignment tools and a level floor or build a rack.

It's just a couple of 'troooungs' and 'brakakakaks'. Simple!

Are you running the OEM spring setup?

When I had my Porsche race car, I used "Smart Strings", basically strings to do the aligment. 90 degree plates on the ground, against the wheels for camber, and string and a tape measure for toe.

At what cost though? 10k for the Penske, and sure you have all these options but if you're not tracking the car at all, then no need to spend that kind of cash for something that's attainable on the street for half the price with the JRZ. Even so these Penske dampers are the race series. So applicable only to the JRZ raceline the 12 31 and 14 31.

Either off the shelf preset or custom spec'd. Agreed no one has the customization that Penske does, but 95% of those looking for really nice suspension won't know what to do with that level of customization.

Edit: if I knew all the things that went into a damper to change it's characteristics you bet I would go all out for some nice Penskes. But there's two problems with that;

1. I don't know a quarter of the options I'd be looking at and what a change any of them would do
2. I haven't had enough suspension experience to know the ride difference between a well setup Penske and a well setup JRZ.

I have one bent Penske left over from my IMSA 300TT that I would sell for 1/2 that. We ran Penskes on everything because of all the parts and service I would never run anything else on an all out race car, now for the street Damptronics. Had to get the plug in.

I did last year for autox since I was in stock class and I still am, only because I haven't had time to swap springs.

Yeah the guys I know who use them and know what to do with them swear by them completely. You can also go find just about any circle track shop/builder and they are also using Penske shocks and can supply parts or even work on them for you.

They are also a lot more durable than you might think. I know people who daily drive on 8300 setups and never have any problems, just because they are expensive doesn't mean they wear out quickly. They use good parts, good seals, and they are engineered well.
